ACPL-M71T-560E

Optoisolators are electronic devices that act as an isolated barrier between high power circuits and low power circuits. One of the most popular optoisolators is the ACPL-M71T-560E, which belongs to the Logic Output family. This article will discuss what application field the ACPL-M71T-560E serves and its working principle.

What is the ACPL-M71T-560E?

The ACPL-M71T-560E belongs to the Optoisolator - Logic Output category and is manufactured by Avago Technologies. It is a digitally addressable, 6-pin DIP optoisolator that contains a gallium-arsenide infrared emitting diode optically coupled to a silicon phototransistor. The device provides electrical isolation of up to 3750Vrms for 1 minute.

Application Field

The ACPL-M71T-560E is used in many different application fields. It is commonly used in consumer electronics, medical equipment, automotive equipment, and industrial equipment. It is frequently used as a voltage sensor in circuit designs, as its isolation capabilities make it ideal for preventing high voltage from flowing into sensitive circuits. In addition, the optoisolator can offer additional protection against electrical noise, over-voltage, and spikes.

Working Principle

The working principle of the ACPL-M71T-560E is simple. The device is composed of a GaAs infrared emitting diode (IRED) that is optically coupled to a silicon phototransistor. When an electrical signal is applied to the input of the optoisolator, the IRED emits light which is detected by the phototransistor. This causes the phototransistor to turn on, allowing current to flow through the output circuit.

The amount of current that is allowed to flow through the output is determined by the electrical signal applied to the input. This enables the ACPL-M71T-560E to be used for current level detection and switching, as well as providing electrical isolation between the input and output. The optoisolator can also be used for monitoring and controlling voltage levels.

Conclusion

The ACPL-M71T-560E is a popular optoisolator belonging to the Logic Output family. It is used in numerous application fields such as consumer electronics, medical equipment, automotive equipment, and industrial equipment. It is composed of a GaAs IRED and a silicon phototransistor, and it provides electrical isolation of up to 3750Vrms for 1 minute. It is used for voltage and current sensing, as well as providing additional protection against electrical noise, over-voltage, and spikes.
